Use the code below to select the first 40 predictors in the meatspec dataset. Use the glmnet package to perform Ridge and LASSO analyses on the 40 predictors. You do not need to build training and test data sets for this exercise.Use 10-fold Cross Validation to pick the optimal lambdas.
Submit your program, output, and any graphs that are generated, and a short paragraph summarizing your results.
library(faraway)
library(glmnet)
data(meatspec,package="faraway")#the dataset meatspec is found in the faraway package
# Getting the dependent variable
y_var <- meatspec$fat
y_var
# Getting the independent variables
x_var <- as.matrix(meatspec[,(1:40)]) #includes the 40 variables V1 - V40
head(x_var,1L)
#continue with program to perform Ridge and LASSO.
